Вопрос:

3. \((4\frac{3}{8}\cdot2\frac{4}{11})+(6\frac{1}{5}-3\frac{7}{15}):2\frac{2}{3}\)

Ответ:

\(4\frac{3}{8}\cdot2\frac{4}{11}=\frac{35}{8}\cdot\frac{26}{11}=\frac{455}{44}\).

\(6\frac{1}{5}-3\frac{7}{15}=\frac{31}{5}-\frac{52}{15}=\frac{41}{15}\).

\(\frac{41}{15}:\frac{8}{3}=\frac{41}{40}\).

\(\frac{455}{44}+\frac{41}{40}=\frac{5001}{440}\).

Ответ: \(\frac{5001}{440}\).
